Abstract
A method and apparatus for transmitting data using an enhanced random access channel procedure are disclosed.
Description
The application is that application number is 200780039465.6, the applying date is on October 27th, 2007, is entitled as the division of the Chinese patent application of " method and apparatus of assigning radio resources and control transmission parameter on Random Access Channel ".
Technical field
The present invention relates to radio communication.
Background technology
In 3GPP UMTS (third generation partner program general land telecommunication system) wireless system, if there is not the dedicated radio link, Random Access Channel (RACH) is up link (UL) transmission channel that is used to transmit data and/or control information.Described RACH is mapped to Physical Random Access Channel (PRACH).
Insert RACH based on time slot A loha (slotted-Aloha) method by wireless transmission receiving element (WTRU), catch indication and then receive from radio access network (RAN).At first, WTRU must obtain channel by the emission preamble, and this preamble has comprised the signature sequence of being selected at random (signature sequence) in one group of predetermined sequence.The transmitting power of initial pre-amble determines that by open Loop Power control parameter is then determined by RAN and broadcasted.
Then, WTRU waits for the indication of catching from Node B, and this is caught indication and upward adopts signal to announce in down link at acquisition indicator channel (AICH).When Node B detected the PRACH preamble that is associated with the RACH trial, its can carry out transmission with indication WTRU at the same signature sequence of loopback on the AICH on PRACH.
If do not detect AICH, WTRU can promote its through-put power by predetermined quantity, and retransmits preamble at next available transmission time slot.This processing will be carried out repeatedly, detects AICH until WTRU, perhaps reaches maximum preamble the number of transmissions.If receive negative response or reached maximum transmission times, the RACH access failure, and in media access (MAC) layer, can carry out rollback (backoff) process.
If affirm AICH by the Node B emission, WTRU can launch the PRACH frame, and this PRACH frame is made up of control section shown in Figure 1A 10 and data division 15.
Preamble and AICH process provide a kind of method that keeps RACH and definite correct through-put power for WTRU.The power of control section 10 is by the constant offset setting from the preamble power of last transmission.The through-put power of data division 15 uses the gain factor that relates to control section to be provided with, and this gain factor is to determine in the mode identical with other UL DPCH.This gain factor is decided by the flare factor that is used for data division.Flare factor 256,128,64 and 32 is considered for the PRACH data division.
With reference to figure 2, AICH is made up of a series of continuous access slots 20.Each access slot is made up of two parts, i.e. acquisition indicator (AI) part 25 and 1024 nothing transmission chip duration parts 30.No transmission time slot part 30 is to keep for possible use in future.The flare factor (SF) that is used for the AICH channelizing is 256.
In existing 3GPP system, the transmission rate of RACH/PRACH is (flare factor of single sign indicating number is 32) that is restricted.A reason implementing this restriction is to avoid when happening suddenly for transmission of high-rate on RACH/PRACH being disturbed by the excessive UL that WTRU causes.When WTRU obtained RACH and inserts, it must select the transformat that is used to transmit independently.Concerning RAN, have no idea dynamically to control the transmission rate of WTRU on RACH/PRACH.

Embodiment
Hereinafter, term " wireless transmitter/receiver unit (WTRU) " is including, but not limited to subscriber equipment, mobile radio station, fixing or mobile contracted user unit, beep-pager or other any equipment that can work in wireless environment.The term of hereinafter quoting " base station " other any interface equipments in Node B, site controller, access point or the wireless environment.
Though this paper describes in the scope of 3GPP UMTS and UMTS terrestrial radio access (UTRA) wireless communication system, but follow-up embodiment and instruction are equally applicable to other wireless communication technologys, Random Access Channel are used for the system of ul transmissions comprising those.
What Figure 1B showed is the frame format of proposing for Physical Random Access Channel (PRACH).The Several Methods of Figure 1B indication is not considered to limit, and these methods can be used separately, but also combination in any to improve the transmission rate of PRACH frame.First method comprises the flare factor (SF) that reduces use on data division 17.Second method comprises the quantity that increases the channel code that is used for data division 17.The third method be included as data division 17 improve order of modulation (for example use 8-PSK, 16-QAM, 64-QAM) and different coding speed.Alternatively, the control section of PRACH frame 12 can be modified to support higher data rate.The reliability of pilot field when the through-put power raising of proposal control section is used high data rate to be increased in.Especially, the power excursion (Pp-m=P between last preamble and the PRACH control section
Message-control-P
Preamble) can depend on transmission rate, rather than have independent value.
RACH/PRACH can realize that this raising of speed may cause the remarkable increase of transformat (the being the time slot form) quantity that need be supported by the PRACH data division.Concerning the control section 10 of existing PRACH, its time slot format only provides two bits in transport format combination index (TFCI) field 35.Thus, the supported number of transport formats of PRACH data division can be restricted to four usually.In order to avoid this restriction, be the new time slot format of control section 12 proposals shown in Figure 1B of PRACH.This new time slot format can provide plural bit in TFCI field 37.For example, if in TFCI field 35, have 8 bits, will be allowed to nearly 2 at the data division 17 of PRACH
8=256 kinds of different time-gap forms.
Concerning this time slot format that comprises two above bits in TFCI field 37 of redetermination, in order to realize backwards compatibility, this time slot format need provide the time slot format coexistence of two bits with previous those in TFCI field 35.Because the base station is current not to have and can understand specific WTRU and be the control section 10 of its PRACH transmission and the means of data division 15 which kind of PRACH type of use, therefore, if these two kinds different PRACH types of PRACH and enhancement mode PRACH exist simultaneously, will bring a difficult problem for the base station is correctly decoded PRACH.
This backwards compatibility problem can be separated into two groups by the radio resource that PRACH is used and handle.A group keeps for the PRACH transmission of using old PRACH form, and another group then keeps for the enhancement mode PRACH transmission of using new PRACH form.This separation can be guaranteed by dedicated radio resource channel (RRC) signaling or broadcasting RRC signaling by RAN.Hereinafter provided three examples, but these examples are not limit or restrictive.
First example shown in Figure 5 is the separation in the time slot that can be used for the PRACH transmission.RAN can keep the time slot of some for using the PRACH transmission of specifying the PRACH form, keeps another group time slot for the PRACH transmission of using another kind of PRACH time slot format simultaneously.What Fig. 5 described is a particular instance of separating by access slot; Other examples also are feasible.
Second example is used for the separation of the scrambling code of PRACH transmission.RAN can keep the scrambling code of some for using the PRACH transmission of specifying PRACH form (for example traditional PRACH), keeps another group scrambling code for the PRACH transmission of using another kind of PRACH form (for example enhancement mode PRACH) simultaneously.The assignment of described scrambling code can also can be announced by the RRC broadcast signaling by more high-rise with the signal announcement.
The 3rd example is the separation of the signature sequence that uses in the PRACH preamble.RAN can keep the signature sequence of some for using the PRACH transmission of specifying PRACH form (for example traditional PRACH), keeps another group signature sequence for the PRACH transmission of using another kind of PRACH form (for example enhancement mode PRACH) simultaneously.Shown an example that how to separate signature sequence in the table 1, wherein P0 to P8 keeps for PRACH, and P9 to P15 keeps for enhancement mode PRACH.Please note that this is a kind of realization of the separation of signature sequence; Alternate manner is feasible equally.
Table 1
Improve data rate according to method disclosed by the invention and may increase the noisiness that is produced.Increase for fear of the excessive noise that is caused by high data rate RACH/PRACH burst, RAN can be configured to the interference that is produced by WTRU is controlled.Especially, before the WTRU of PRACH frame transmission, RAN can be used for transmitting the peak transfer rate and/or the power of PRACH frame to the WTRU indication.As an alternative, can a pre-configured permission (for example by the RRC broadcast signaling) begin transmission, and alternatively, when WTRU transmitted, this permission can be readjusted by UTRA network (UTRAN) on enhanced RACH to allow WTRU.
The information of announcing to WTRU with signal from RAN can limit the systematic influence that is caused by the PRACH frame effectively, allows WTRU to select high-transmission block size and maximization RACH access efficiency simultaneously.Disclose a kind of license type signaling mechanism here, wherein RAN can be for the maximum UL stock number of PRACH frame transmission use to the WTRU indication.Also proposed the non-exhaustive list of follow-up example metrics and parameter, described tolerance will be used to determine being what kind of UL resource of enhancement mode PRACH transmission permission individually or in the combination in any mode.
First example is a maximum power ratio, the maximum power ratio between this maximum power ratio value representation enhancement mode PRACH data division 17 and the control section 12, or the data division 17 of enhancement mode PRACH and the maximum power ratio between the preamble power.This maximum power ratio is that of WTRU through-put power may measure.It is a kind of method that the noise that produces in UL of control WTRU increases or disturbs that the power of WTRU is controlled.This power control can be carried out by the base station.
Be used for determining to be maximum transmission power for second example of the tolerance of what kind of UL resource of enhancement mode PRACH transmission permission, this maximum transmission power represents that WTRU can be used to transmit the maximum gross power of the PRACH frame with enhanced data part 17 and control section 18.This maximum gross power can be used as absolute value (for example 20dBm) to be determined, also can be used as with respect to the relative power of preamble power and determines.The same with previous example, by the power of control WTRU, can effectively control the noise that is caused in UL by WTRU increases or interference.This power control can be carried out by the base station.
The 3rd example of tolerance is maximum RACH transmission block size.To the definite permission UTRAN of this amount by the time quantum that uses RACH is controlled the interference that WTRU produces.
The 4th example of tolerance is Transmission Time Interval (TTI) size.
The 5th example of tolerance is the maximum time amount (for example TTI quantity) that WTRU can transmit.
License Value can be mapped to certain index, and wherein this mapping is for known to WTRU and the RAN.Described mapping can by RAN broadcasting on the BCCH/BCH, by the configuration of high-level signaling more or in WTRU equipment by pre-configured.
Proposed various mechanism hereinafter, transmitted above-mentioned information to allow RAN.These mechanism can be used individually or with combination in any.
In one embodiment, as shown in Figure 3, control information is arrived WTRU with existing AICH or similar channel transfer.Especially, RAN utilizes the indication of catching that sends between preamble and PRACH frame to come to WTRU indication peak transfer rate.Shown proposed AICH structure among Fig. 3.The first 50 of AICH access slot can have with existing AICH in identical meaning, before then comprised control information for the decline 40 of reserve part 30.
In example embodiment, the number of chips in the above-mentioned example can be held: the first of AICH or AI part 50 can comprise 4096 chips, and second portion 40 can comprise 1024 chips.Use SF 256 channel codes, can on 1024 chips, transmit sequence with 8 real-valued signal.Can be each control information tier definition predetermined symbol sequence, for example signature sequence.On RAN and WTRU, the mapping between symbol sebolic addressing and the control information index should be known; This mapping can broadcast by RAN, by high-level signaling configuration more or by pre-configured.
As an alternative, last 1024 chips 40 of AICH time slot can be interpreted as comprising the new bit field (for example 4 bits) of control information index, and wherein chnnel coding can be used for improving the decoding reliability of bit field.
As an alternative, control permission can use following any one transmit: as the existing enhancement mode of PRACH frame indication " permission " insert door channel (enhanced access gate channel) (E-AGCH) with enhancement mode reverse swing door channel (enhanced reverse gate channel) (E-RGCH); Forward access channel (FACH) transmission channel or similar channel; And Broadcast Control Channel (BCCH) logic channel that is mapped to broadcast channel (BCH) transmission channel.In this case, control information is broadcasted in whole sub-district, and this control information both can be used the WTRU of PRACH total by all, also can with signal separately announcement give the WTRU that uses RACH/PRACH.In addition, we can also use other new or existing physical layer signalings and/or L2 control channel to come the transmitting control permission.
RAN can judge that the peak transfer rate of WTRU and/or each successfully capture the power of the WTRU of RACH by preamble mechanism.This judgement can independently be made or be guided by WTRU.
RAN can make this judgement independently for each WTRU that successfully captures channel.An example that is used for the tolerance of this judgement is the restriction in the UL interference.Though very effective when single WTRU captures the RACH channel, when an above WTRU transmitted on RACH, it was invalid to cause.In the later case, might assign higher rate/power, but this WTRU but may not need this speed/power for WTRU.The extra assignment that relates to this WTRU will be lost, but other WTRU but can not use this assignment.
In the method, RAN attempt based on the UL interference-limited and in WTRU designated capabilities, will use the probability of this overhead provision to maximize simultaneously.For reaching this purpose, RAN can require the indication about WTRU buffer memory occupancy.Higher occupancy means the probability of higher use overhead provision.WTRU only need provide the rough indication (for example basic, normal, high, very high) of buffer memory occupancy.This information can be announced with signal with some kinds of replacement methods in the RACH preamble.For example, telegram end can be appended to the preamble message that has the indication of buffer memory occupancy.As an alternative, this information also can be coded in the preamble signature sequence; Be each buffer memory occupancy grade and keep one group of signature sequence.
Fig. 4 is the functional block diagram 300 with the part in the exemplary radio communication system of WTRU 210 and Node B or base station 220.WTRU 210 and base station 220 are carried out two-way communication each other, and all are configured to carry out the method that is used to improve the message transmission rate on Random Access Channel as one of above-mentioned embodiment.
